Go to the Roku home screen, select “Search,” and enter in whatever
you want to watch (again, your phone keyboard comes in handy
here). Up comes a list of where you can watch it, and how much (if
anything) it costs. A search through my channels for 500 Days of
Summer let me know I could rent it from Amazon, Vudu, or
Blockbuster, for between $2.99 and $3.99. Searching for Jiro
Dreams of Sushi brought up the same results, plus the option to
stream for free on Netflix or Amazon Prime. The more channels you
add, the more options you’ll get, and search is impressively well
integrated across Roku’s most popular channels, from Vudu to
Netflix to Crackle.
